ENGINE-LUBRICATOR.

Specification of Letters Patent. v

Patented J an. 21, 1913.

To all whom, t may concern:

Be it known that I, EMIL A. NELSON, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State. of Michigan, have invented cer-v tain new and useful Improvements inEngine-Lubricators, of which the following .is

a specication, reference being had therein section'through a portion of the engine cas- Wang L.

ing showing the lubricator-attached there- 2 is a plan view partly in section; and Fig. 3 is asection through the plug.

A are engine cylinders, B is a common crank case therefor, and C is a conduit or stack for venting the crank case. This stack is secured to a member D which is bolted or otherwise secured to a bearing E onthe crank case and which in addition to its function as a vent forms a portion of the lubricating system. I n detail, the member D is provided on its outer end with an enlargement F in which a screen G 1s located. Beyond this screen is a dish-shaped cap member H which is secured by a bolt I and is connected to a conduit J through which the supply of lubricant is fed by any 'suitable pumpI or propelling de* ce '(not shown). On the inner side of the screen the chamber withinthe member F is connected by passages J surrounding the air vent passa e K and separated therefrom by he passages J lead to a` chamber M which at its with la port N with a longitudinally extending channel O in the crank case fro-m which the lubricant is distributed to various bearings (not shown). Above the chamber M is a valve P controlling the discharge to aplurality of conduits Q leading to the several engine cylinders.

It is one ofthe objects of the invention to provide means of for the several engine cylinders by which the quantity of lubricant can be regulated and accurately proportioned to the several cylinders. This is accomplished by forming the valve P so that in every 4position of adjustment thereof the ports communicating with lchamber P 1n open -single member D forms support for the air bottom communicates lubricating the pistonsk Applicationled January 27, 1912. Serial No. 673,837.

the several conduits Q will be equal or proportioned. AP is a hollow tapering plug with a central communication with the chamber M and oppositely extending ports P2 which respectively register-with the conduits Q. The upper. end of the plug passes out from the member D and has sleeved thereon the spring R for yieldably holding the valve to its seat and may be rotatably adjusted by any suitable means (not shown). The conduits Q are connected with the valve casing by suitable coupling unions S which permit o-f attach'ng or detaching the member D.

With the construction as shown, the

the straining chamthe valve case tor the ber for the lubricant,

and the adjustment and distributing valve,

forms the connection between the lubricant supply and the channel O in the crank case, the flow through the latter being unrestricted. In addition to the valve P, the flow of lubricant in the conduits Q is restricted by perforated diaphragms T, secured by the couplings S.

What I claim as my invention is:

1. The combination with an engine casing having a vent passage or stack, and a lubricant distributing channel in the Wall thereof, of a member attached to sai-d casing forming the connector for said stack and having a lubricant chamber therein communicating with said distributing channel.

2. The combination with an engine casing, of a member secured to said casing having a vent conduit or stack attached thereto and coupling the same to a vent opening in said case, said member being also provided with lubricant channels thereinpand having an enlargement containing a screen through which the lubricant is passed.

3. The combination with an engine casing, of a member attached thereto forming As shown, the valve vent or stack. It also the base of a vent sta-ck communicating connected to said coupler having the flow chamber at the opposite end of said memof lubricant therethrough proportioned by ber, and a Valve controlling and restricting said valve. the flow 'of lubricant from said chamber to 4. The combination With an engine casa plurality of conduits. 5 ing, of a member D attached thereto hav' In testimony whereof I aliX my signature 15 ing the enlargement E and the screen G in presence of two witnesses.
